First of all I make you clear that cubers can figur their xps required of very next level out by putting mouse curser on top-right side of chesscube screen at area where level info. is situated.Second, newly registred cubers gets 180 xps that of level 6 by default.

The unit of xps required for each level from level 7 to level 300 are stated below:

Explain:1. from Level 7-8, a user must have done 122 Xp to reach level 82. from Level 9-10, a user must have done 168 Xp -3. from Level 99-100, a user must have done 1186 Xp-4. from Level 199-200, a user must have done 3511 Xp to reach level 200

It seems that is growing up the xp between a level to achieved up to, every level from 7-200 i growing up.

But why.?5. from Level 299-300, a user must have done 2241 Xp, to reach the level of 300. why from 299-300 is less than 199-200.

http://bit.ly/2cy42OBWell, the 300 level is not 2718k but 2860k, I would request you to please modify it. Because, people like me aimed for 300 level, and had a plan accordingly, which failed badly. I reached 2718k on time, but when I saw that 300 is 2860, well.So, please edit it, the proof is in link.
